@neural_avb Women are sooo practical!

[Kostas Karolemeas @VoxelPerfect]

@Surendar__05 that happens when the core business is advertising.

[Kostas Karolemeas @VoxelPerfect]

@jmao0001 @ash_twtz I know. I mentioned harness (the coding agent) + LLM.

[Kostas Karolemeas @VoxelPerfect]

@steipete you are about to release OpenHello?

[Kostas Karolemeas @VoxelPerfect]

@Star_Knight12 16.2.4 is too old

[Kostas Karolemeas @VoxelPerfect]

I was about time!

[OpenAI @OpenAI]

Rolling out today as a preview on iOS and Android in all supported regions.

Support for connecting your phone to the Codex app on Windows is coming soon.

@jmao0001 @ash_twtz Is it better? For large complex projects you need a combination of a good model and a good agent harness. Who cares if it is proprietary or open-source as long as you get the best outcome.

[Kostas Karolemeas @VoxelPerfect]

Be honest, what is this "Be honest, which x is best at y?" allover X?

[Kostas Karolemeas @VoxelPerfect]

@ash_twtz Their core business is Ads. They built Android out of the fear of loosing mobile as an Ad platform. They cannot succeed with that mentality.

@KaiXCreator GPT 5.5 (Codex used to be a separate model now included in 5.5)

[Kostas Karolemeas @VoxelPerfect]

@Taniyatweets_ MacBook with no 2nd thought!

[Kostas Karolemeas @VoxelPerfect]

@haider1 Is it a matter of a world model or just closing the loop by letting the model see the result and improve based on feedback like a human would do? Even humans that may be able to predict the consequences of their actions, still rely on feedback.

[Kostas Karolemeas @VoxelPerfect]

@HopeForTheWorl1 @OpenAIDevs @cursor_ai Yes this is available already in Github Copilot. However, you can say that you do not want any code changes and it will respect that.

[Kostas Karolemeas @VoxelPerfect]

@elonmusk How many languages does it support in good quality?

[Kostas Karolemeas @VoxelPerfect]

I tried both and eventually chose Codex as a more complete application I can rely on for complex tasks.

[Kostas Karolemeas @VoxelPerfect]

It’s fascinating watching Codex vs Claude turn into the Apple vs Google of AI coding tools.
People aren’t just comparing capabilities anymore - they’re forming identities, tribes, and loyalties.

[Kostas Karolemeas @VoxelPerfect]

@adcock_brett @hark_labs It was about time for something new!

We taught two F.03 robots to clean a room and make a bed in under 2 minutes - fully autonomous.
